Hi, The main reason for the patch series is to have a bit more manageable debug info for PS/2 init sequence: raw i8042 debug is way too noisy, one has to decode sliced commands by hand, etc, etc. With proposed changes you get a nice parsed command flow: [14421.985416] __ps2_command: psmouse serio2: f5 [] - 0/00000000 [] [14421.993112] __ps2_command: psmouse serio2: f6 [] - 0/00000000 [] [14422.007738] __ps2_command: psmouse serio2: e1 [] - 0/00000000 [03 04] [14422.042522] __ps2_command: psmouse serio2: e2 [81 4a 80] - 0/00000000 [] [14422.057091] __ps2_command: psmouse serio2: e2 [2c] - 0/00000000 [20] [14422.057118] psmouse serio2: trackpoint: Elan TrackPoint firmware: 0x04, buttons: 3/3 [14422.072062] __ps2_command: psmouse serio2: f3 [64] - 0/00000000 [] [14422.086839] __ps2_command: psmouse serio2: e8 [03] - 0/00000000 [] [14422.094306] __ps2_command: psmouse serio2: e6 [] - 0/00000000 [] [14422.094504] input: TPPS/2 Elan TrackPoint as /devices/rmi4-00/rmi4-00.fn03/serio2/input/input33 [14422.128629] __ps2_command: psmouse serio2: f4 [] - 0/00000000 [] Additionally libps2 now can handle command and parameter byte retransmissions and we relaxed rules for getting initial ACK to the command byte, which hopefully will help properly detect devices that are not silent when we start probing them. Thanks.
